UNITED STATES PATENT OFFICEQ CI-IARLES A. DEARBORN, OF NEWV YORK, N. Y.

SEWING-MACHINE STAND.

SPECIFICATION forming part of Letters Patent No. 413,650, dated October29, 1889.

Application filed December 1, 1888. Serial No. 292,390- (No model.)

To all whom it may concern:

Be it known that I, CHARLES ALMY DEAR- BORN, mechanical engineer, of thecity, county, and State of New York, one of the United States ofAmerica, have invented a certain new and Improved Sewing-MachineStand,of which the following is a specification.

The object of the invention is to design a combined sewing-machine standand writingtable, in which the machine when not required for use may belowered below the top surface of the stand without encroaching upon thespace necessary for the knees of the operator of the machine or user ofthe table; and it consists, essentially, of a platform arranged tosupport the sewing-machine and hinged to a swinging frame pivotallyconnected to the stand below its top, the said platform being placed inthe opening formed in the top of the stand and arranged to fold belowit, so as to carry the machine attached to the platform underneath theupper surface of the stand, where it is covered by a top pivoted on thestand and arranged so that it may be swung over the opening when themachine has been folded below, the whole being arranged in detailsubstantially in the manner hereinafter more particularly explained.

Figure 1 is a perspective view of the machine folded below the table andthe top closed. Fig. 2 is a perspective View with the machine foldedbelow the table and the top open. Fig. 3 is a perspective View,partially in section, showing the swinging platform set to carry thesewing-machine when in its propor position for use. Fig. 4 is asectional elevation with the machine folded below the table. Fig. 5 is aperspective sectional View showing the connection between the pivotedtop and stand.

In the drawings, A represents a swinging frame hinged at a to the bottomB. On the upper end of the frame A, I hinge the platform C, to which thesewing-machine D is hinged or otherwise secured, the said .platformbeing narrower than the opening in the stand.

E is a spring connected to the frame A and arranged to act against theplatform 0, so as to counterbalance in ameasure the Weight of thesewing-machine D.

F is a roller journaled on the outer edge of the platform 0 and designedto run on the track G when the machine is lowered into the positionindicated in Figs. 2 and 4. Then the top H is thrown back into theposition shown in Fig. 2, the operator has merely to seize the machineand pull it upwardly. The action of the spring against the platform Cand of the roller F on the track G greatly facilitates the action andmakes the raising of the machine an extremely easy matter. The momentthat the platform 0 is raised into a horizontal position the saidplatform will naturally slide forward, and its front edge will slip overand rest upon the ledge I.

I11 order to lower the machine, the operator has merely to push themachine back until the platform 0 is clear of the ledge I, when theweight of the machine will carry it down, and the action of the roller Fagainst the slanting curved track G pushes the swinging frame Abackwardly into the position indicated in Fig. at. This swinging forwardand backward movement of the frame Apermits the machine to be drawnforward close to the operator when it is set for use, and when droppedbelow the table the roller F, acting on the slanting curved track G,causes the frame Ato tilt back and carry the machine away from the frontof the table, so as to leave as much space as possible for the knees ofthe party sitting at the table.

In order to protect the machine from dust when set below the table, Iplace a slanting board J, extending from the front edge of the bottom Bto the ledge I, and a vertical back board K, the slanting board J beingdesigned to take up no more room than is necessary to properly containthe sewing-machine, so that the full space obtainable is secured for theknees of the operator using the sewing-machine or the party occupyingthe table. The top H, which is arranged to act as an extension-tablewhen the machine is in use and as a writing or ordinary table when itisswung over the machine, when set below the table, is connected to theframe by a strong center pin L, rigidly secured to the semicircularplate M, which is fastened upon the bottom of the top H. The pin L issituated a little distance from the edge of the top H and is insertedinto a hole made in the top plate N, and is held in position by aspring-washer 0 IOO and pin. P is a groove in the top plate l to receivethe lug when the plate is swung around. A lug P is formed upon orattached to the plate N and is designed to engage, when the top H isswung around in the position shown in Fig. 2, with a small bracket Q,attached to the top plate N. This bracket prevent-s the top H swingingaround too far, and it also stays the top so as to prevent itsunsupported end from sagging. The mannerin which the top overlaps thestand also tends to strengthen the support.

hat I claim as my invention is 1. A swinging frame hinged or pivoted atits lower end to the bottom B at a point below an opening in the top ofa stand, in combination with a platform hinged to the swinging frame anddesigned to support a sewin g-machine, substantially as and for thepurpose specified.

2. A swinging frame hinged or pivoted at a point below an opening in thetop of a stand, a platform hinged or pivoted to the swinging frame anddesigned to support the sewing-machine, in combination with a springdesigned to act against the platform to partially counterbalance theweight of the sewingmachine, substantially as and for the purposespecified.

3. A swinging frame hinged or pivoted at a point below an opening in thetop of a stand, a platform hinged to the swinging frame and designed tosupport the sewing machine, a roller j ournaled on the front edge of theplatform, in combination with a slanting curved track for the roller,and aledge to support the platform in a horizontal position,substantially as and for the purpose specified.

4. A swinging frame hinged or pivoted at a point below an opening in thetop of a stand, a platform hinged or pivoted to the swinging frame anddesigned to support the sewing-machine, a roller journaled on the frontedge of the platform, in combination with a spring designed to actagainst the platform to partially counterbalance the weight of thesewing-machine, a slanting track for the roller, and a ledge to supportthe platform in a horizontal position, substantially as and for thepurpose specified.

5. A swinging frame hinged or pivoted at a point below an opening in thetop of a stand, a platform hinged or pivoted to the swinging frame anddesigned to support the sewing-machine, in combination with a toppivoted so as to overlop the top of the stand when its major portion isthrown clear of the stand, and to swing over to cover the opening in thetop of the stand to formihe stand into an ordinary table.

0. The plate M, havingaeenter pin Lsecured to it and fastened to thebottom of the top H, a lug P, fixed to the plate M and designed to fitbelow the bracket Q, which is attached to the top plate N, substantiallyas and for the purpose specified.
